INTRODUCTION

Global warming is the rise in the average temperature of Earth's atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century, Earth's mean surface temperature has increased by about 0.8 °C (1.4 °F), with about two-thirds of the increase occurring since 1980.

It’s a fact that our world is warming.Scientific consensus:Global warming is primarily induced by human activities, principally because of greenhouse gas emissions from combustion of fossil fuels.Increased greenhouse gas emissions will result in increased average global temperatures.

Atmospheric concentrations of greenhouse gases are the highest in at least 650,000 years (as measured by Antarctic ice core samples)*Our energy future choices and global warming are inextricably linked.

THE TOP MOST CAUSES OF

GLOBAL WARMING

1. Carbon dioxide emissions from fossil fuel burning power plants: Our ever increasing addiction to electricity from coal burning power plants releases enormous amounts of carbon dioxide into the atmosphere. 40% of U.S. CO2 emissions come from electricity production, and burning coal accounts for 93% of emissions from the electric utility industry .Every day, more electric gadgets flood the market, and without widespread alternative energy sources, we are highly dependent on burning coal for our personal and commercial electrical supply.

2. Global Warming Cause: Carbon dioxide emissions from burning gasoline for transportation: Our modern car culture and appetite for globally sourced goods is responsible for about 33% of emissions in the U.S. With our population growing at an alarming rate, the demand for more cars and consumer goods means that we are increasing the use of fossil fuels for transportation and manufacturing. Our consumption is outpacing our discoveries of ways to mitigate the effects, with no end in sight to our massive consumer culture.

3. Methane emissions from animals, agriculture such as rice paddies, and from Arctic seabeds: Methane is another extremely potent greenhouse gas, ranking right behind CO2. When organic matter is broken down by bacteria under oxygen-starved conditions (anaerobic decomposition) as in rice paddies, methane is produced. The process also takes place in the intestines of herbivorous animals, and with the increase in the amount of concentrated livestock production, the levels of methane released into the atmosphere is increasing. Another source of methane is methane clathrate, a compound containing large amounts of methane trapped in the crystal structure of ice. As methane escapes from the Arctic seabed, the rate of global warming will increase significantly.

4. Global Warming Cause: Deforestation, especially tropical forests for wood, pulp, and farmland: The use of forests for fuel (both wood and for charcoal) is one cause of deforestation, but in the first world, our appetite for wood and paper products, our consumption of livestock grazed on former forest land, and the use of tropical forest lands for commodities like palm oil plantations contributes to the mass deforestation of our world. Forests remove and store carbon dioxide from the atmosphere, and this deforestation releases large amounts of carbon, as well as reducing the amount of carbon capture on the planet.

5. Global Warming Cause: Increase in usage of chemical fertilizers on croplands: In the last half of the 20th century, the use of chemical fertilizers (as opposed to the historical use of animal manure) has risen dramatically. The high rate of application of nitrogen-rich fertilizers has effects on the heat storage of cropland (nitrogen oxides have 300 times more heat-trapping capacity per unit of volume than carbon dioxide) and the run-off of excess fertilizers creates ‘dead-zones’ in our oceans. In addition to these effects, high nitrate levels in groundwater due to over-fertilization are cause for concern for human health.

EFFECTS OF GLOBAL W

ARMING

6. Global Warming Effect: Rise in sea levels worldwide : Scientists predict an increase in sea levels worldwide due to the melting of two massive ice sheets in Antarctica and Greenland, especially on the East coast of the U.S. However, many nations around the world will experience the effects of rising sea levels, which could displace millions of people. One nation, the Maldives, is already looking for a new home, thanks to rising sea levels.

7. Global Warming Effect: More killer storms: The severity of storms such as hurricanes and cyclones is increasing, and research published in Nature found:“Scientists have come up with the firmest evidence so far that global warming will significantly increase the intensity of the most extreme storms worldwide. The maximum wind speeds of the strongest tropical cyclones have increased significantly since 1981, according to research published in Nature this week. And the upward trend, thought to be driven by rising ocean temperatures, is unlikely to stop at any time soon.”

8. Global Warming Effect: Massive crop failures: According to recent research, there is a 90% chance that 3 billion people worldwide will have to choose between moving their families to milder climes and going hungry due to climate change within 100 years.“Climate change is expected to have the most severe impact on water supplies. “Shortages in future are likely to threaten food production, reduce sanitation, hinder economic development and damage ecosystems. It causes more violent swings between floods and droughts.”" – Guardian: Global warming causes 300,000 deaths a year

9. Global Warming Effect: Widespread extinction of species: According to research published in Nature, by 2050, rising temperatures could lead to the extinction of more than a million species. And because we can’t exist without a diverse population of species on Earth, this is scary news for humans.“Climate change now represents at least as great a threat to the number of species surviving on Earth as habitat-destruction and modification.” Chris Thomas, conservation biologist at the University of LeedsWidespread species loss and lists of endangered species just keep growing. This is a concerning matter on many fronts.

10. Global Warming Effect: Disappearance of coral reefs: A report on coral reefs from WWF says that in a worst case scenario, coral populations will collapse by 2100 due to increased temperatures and ocean acidification. The ‘bleaching’ of corals from small but prolonged rises in sea temperature is a severe danger for ocean ecosystems, and many other species in the oceans rely on coral reefs for their survival.

SOME IMPORTANT STEPS TO

ERADICATE GLOBAL WARMING

1.CHANGE A LIGHT Replace regular bulbs with compact fluorescent light (CFL) bulbs. They consume less power then ordinary bulbs and have longer lifetime. Some countries have completely banned the usage of ordinary bulbs and force the common public to use CFL bulbs.These is a method to reduce global warming

2.DRIVE LESS By driving less you are not only saving fuel but also helping in reducing global warming. Also, look out for other possibilities, for eg: car pooling. If you have colleagues who live in the same area then you can combine trips. If you need to go to a local market then either walk or go by cycle. Both of them are great form of exercise

3.RECYCLE MORE Try to use the disposable products into some other form. Just don’t throw them away. You can recycle almost anything for eg: paper, aluminum foils, cans, newspapers. By recycling you can help in reducing landfills .

4.CHECK YOUR TYRES When you drive make sure your tyres are inflated properly. If not, then obviously they will consume more fuel. Keep your engine properly tuned and drive less aggressively. Aggressive driving and frequent applying of brakes hampers the engine and can lower the mileage of your car.

5.USE LESS HOT WATER Buy energy saving geysers and dishwasher for your home. Avoid washing clothes in hot water. Just wash them in cold or warm water. Avoid taking frequent showers and use less hot water. It will help in saving energy require to produce that energy.

6.AVOID PRODUCTS WITH LOT OF PACKAGING

Just don’t buy products with lot of packaging. When you buy such products you will end up in throwing the waste material in the garbage, which then will help in filling landfill sites and pollute the environment. Also, discourage others from buying such products.

7.PLANTING TREES Planting trees can help much in reducing global warming then any other method. They not only give oxygen but also take in carbon dioxide, during the process of photosynthesis, which is the main source of global warming.

8.USE GREEN POWER Purchase environmentally friendly green power electricity. Green power is generated from renewable energy sources such as the sun and wind, producing lower greenhouse .Locate participating green power utilities in your area by visiting the EPA website.Other options for creating a greener home include installing solar panels or generating your own green power .

9.EAT FRESH AND LOCAL FOOD FOR HEALTHY ENVIROMENT

There has been an influx of organic food in supermarkets over the past several years. But of equal importance to consider is where that food is coming from. For example, how much of the produce in your supermarket is being transported halfway around the world? Check the stickers on those apples and peaches and you’ll see ” Produce of Chile”, “Mexico”, or “China”. Also important to note: how much of that food is actually in season? The transportation of food is a major contributor to greenhouse gases.Easy ways for you to get low carbon food are:•Buying things that are actually in season.•Buying locally-grown fruits and vegetables at farmers markets.•Joining a CSA.

10.SPREAD THE AWARENESS Always try your best to educate people about global warming and it’s causes and after affects. Tell them how they can contribute their part by saving energy that will be good for the environment. Gather opportunities and establish programs that will help you to share information with friends, relatives and neighbors.

SO FRIENDS, TRY U R LEVEL BEST
